Turn number worksheet photos into flashcards with AI
Photograph a page of number problems, a place value chart or handwritten notes. DeckOwl reads the text and builds flashcards you can review on a spaced schedule.
Why build your own number flashcards from images
Printable number flashcard sets rarely match the exact skill your class is working on. A photo of your own worksheet or chart gives you image-based number flashcards that fit the lesson, with the same numbers and wording your teacher used.
- Photos of number charts, worksheets and handwritten notes are read with text recognition.
- Cards mix digits, number words and worked examples from your own material.
- Spaced repetition schedules review so you spend time on the facts you miss.
- Free plan studies in the browser; Plus exports to PDF, DOCX, Anki and CSV.
Reads photos of pages
Snap a picture of a worksheet or chart. Text recognition pulls out the digits and the wording around them.
Spaced repetition
Cards you miss come back sooner, and cards you know move further apart, so number facts stick.
Quizzes from the same material
Turn the same source into multiple choice or short answer questions with explanations when you want to test yourself.
How it works
Upload your image or file
Add a photo, PDF, DOCX, PPTX or plain text notes that contain the numbers you need to learn.
Review the generated cards
Check the front and back of each card and edit any digit or label that the recognition got wrong.
Study on a spaced schedule
Work through your deck in the browser and let spaced repetition decide when each card returns.
DeckOwl reads text from images, so a page of place value problems or a table of multiplication facts becomes question and answer cards in one step. You can then add cards for anything the photo missed.
Start with the free plan to try a few generations in the browser. Plus adds unlimited generations and exports to PDF, DOCX, Anki and CSV if you want to print or move your cards.

Frequently asked questions
How should I write number flashcards for place value?
Put a number such as 3,725 on the front and ask for the place value of one digit. The back should name the place and the digit's value, such as hundreds, or 700.
Should number flashcards show digits or number words?
Use digits on one side and words on the other for a few weeks, then reverse them. Mixing both forms helps with reading large numbers and with word problems.
Can I export my number flashcards to Anki or print them?
Yes. Export to PDF, DOCX, Anki and CSV is part of the Plus plan, which is $99.90/year or $9.99/month and includes unlimited generations. The free plan lets you study in the browser without exports.
Do I need a credit card to try it?
No. The free plan gives you 5 generations a week with no credit card needed to start, and students get 40% off with a school email.
